Introduction

The software development industry is scaling at new heights each day, especially with the adoption of DevOps. According to a research report from Statista, 80% of the respondents consider DevOps extremely important for software development.

Even though DevOps continues to dominate software development, there is still confusion about what exactly DevOps means. Is DevOps a process, or a culture, an approach, a methodology, or an amalgamation of all these things? In whichever way you give the DevOps definition, it represents a journey. And no matter whether you are a beginner, intermediate, or an expert in DevOps, we are here to solve your queries, such as:

  • What is DevOps?
  • How DevOps works?
  • What is DevOps Lifecycle?
  • What are the Benefits of DevOps for you?
  • What are DevOps Tools and DevOps Toolchain?
  • Which are the best DevOps practices?
  • What is DevSecOps, and how does it relate to DevOps?
  • Who is a DevOps engineer, and what are DevOps engineer skills, roles and responsibilities?

 

What is DevOps?

 

As the name suggests, DevOps is a combined approach of Software Development (Dev) and IT Operations (Ops). Thus, DevOps is a union of technology, people, and processes to deliver continuous value to the customers. Notably, DevOps is not a specific technology, framework, or set of standards. DevOps users embrace it as a ‘DevOps Culture’ or sometimes as ‘DevOps Environment.’ It promotes better communication and collaboration between the teams.

DevOps

 

Let us understand the technical definition of DevOps.

DevOps Definition

In technical terms, the DevOps definition can be given as :

DevOps is a combination of cultural philosophy, set of practices, and tools that integrate and automate between software development and IT operations team. It emphasizes rapid software development by team empowerment, cross-functional collaboration, simplified communication, and technology automation.

 

Whereas, the scientists from CSIRO and SEI define DevOps as:

DevOps is a set of practices to reduce the turnaround time from committing a change to a system and implementing that change into a production environment while maintaining high quality.

 

In simple interpretation, DevOps is defined as the adoption of an iterative and continuous software development approach, automation, and maintenance. To understand DevOps, you need to know where it came from? Or what’s the History of DevOps? Here is a quick intro of how we got the DevOps.

History Of DevOps

Until 2000, software was built, deployed, and updated using the waterfall model. It is a linear approach to large-scale development. So, software development teams would spend months of time developing the code. And spent several other months integrating the code. Next, the testing and QA team would spend more time on testing the code. This results in huge risks and an enormous amount of time to go live.

To speed up the development process and quality, development teams started using an iterative approach. This iterative approach was known as Agile Software Development or Agile Methodology. These agile practices were more efficient till 2007. After that, software development communities raised a concern that they feel a fatal level of dysfunction.

To overcome all the dysfunctions, Flickr engineers John Allspaw and Paul Hammond represented their own DevOps-like methodology at a conference in 2009. Their title stated, “ 10+ Deploys per Day: Dev and Ops Cooperation at Flickr “. The same year, a software consultant named Patrick Debois organized the first DevOps Day in Belgium. The hashtag ‘#DevOps’ was used, and then more DevOps Days were held worldwide. Thus, the term DevOps came into existence.

Let us move further and understand how DevOps works through the DevOps Lifecycle.

How DevOps works: The complete DevOps Lifecycle

In DevOps Model, the development and operation teams are not isolated. They work together as a single team through the entire DevOps Lifecycle. From development, implementation, testing to operations, they are not limited to any single function. Whereas, in some units, quality assurance and security are also part of the DevOps Lifecycle. The involvement of the security team in the DevOps lifecycle is sometimes referred to as DevSecOps.

This DevOps team automates the processes that were handled manually. They also utilize modern technology stacks and tools to operate quickly and reliably. DevOps teams have tools for each phase of the DevOps Lifecycle. These tools help DevOps engineers accomplish their tasks independently without utilizing more resources. This is how DevOps works.

Knowing DevOps is incomplete without understanding the DevOps Lifecycle, So here is a quick definition of DevOps Lifecycle:

DevOps Lifecycle is nothing but a set of iterative, automated, and continuous development processes designed for rapid software development process while maintaining high quality.

DevOps Life Cycle

 

A standard DevOps Lifecycle consists of 7 phases. Here are they

  1. Continuous Development
  2. Continuous Integration
  3. Continuous Testing
  4. Continuous Monitoring
  5. Continuous Feedback
  6. Continuous Deployment
  7. Continuous Operations

 

These 7 phases of DevOps lifecycle are continuous, iterative, and allow improvement throughout the software development process. Let us dive deep into each step to understand the DevOps lifecycle in a better way.

1. Continuous Development

Continuous Development is the first and foremost phase of the DevOps lifecycle. In this phase, planning and coding of the software take place. The version of the project is also decided during the planning. At the same time, software developers write the code for applications. The planning does not require any primary tools, but there are certain tools for maintaining the code. While developing a source code begins by choosing a development language. Python, C, C++, Ruby, and JavaScript are some of the DevOps most popularly used languages.

I. What is Continuous Development in DevOps

Continuous development in DevOps began like an agile software development methodology. Instead of developing software as a whole, updates are done in a continuous flow in a large batch. Software is developed piece by piece to deliver it to clients as soon as it gets tested.

 

Continuous development offers enormous benefits such as:

 

  • Improved end software quality
  • Easier updation of changes
  • Quickly fixing of bugs and errors
  • Manage overall project risk
  • Improve productivity
  • Save time and resources

2. Continuous Integration

Continuous Integration, generally known as CI, is one of the most important phases of DevOps Lifecycle. Continuous integration is a software development practice where developers need to commit frequent changes to the source code. The changes occur daily or at a gap of a few days . The code is compiled and goes through unit testing, integration testing, packaging, and code review. Thus, the code with new functionalities is continuously integrated with the existing source code.

I. What is Continuous Development in DevOps

Continuous Integration (CI) is a DevOps practice to automate the integration of changes in code from multiple developers into a single repository. After the integration, automated tests and builds are run. Here, automated tools are used to check the builds and codes before the integration. The main goal of Continuous Integration (CI) is to assure quality software, reduce validation and new software update time.

II. Continuous Integration Process

In the continuous integration process, developers frequently update to a shared repository. Before each update, developers may sometimes run a local unit test just to verify code before integration. Whereas continuous integration service automatically builds and runs unit tests on the updated code to check the errors.

Generally, the continuous integration process consists of 4 significant steps. These steps are:

  1. Source Control (Commit Change)
  2. Build (Run Build And Unit Tests)
  3. Staging (Deploy To Test Environment And Run Tests)
  4. Production (Deploy To Production Environment)

Continuous Integration Process

 

Continuous Integration is the most important phase of DevOps lifecycle and has many benefits to offer. Here are the top benefits of continuous integration.

III. Benefits of Continuous Integration

Here is the list of benefits offered by continuous integration

  • CI can find bugs and errors quicker through frequent testing.
  • Continuous Integration delivers updates at a more frequent rate to the customers.
  • Reduce last-minute chaos and risk of the project.
  • CI helps organizations to scale better and quicker.
  • It improves the feedback loop by providing faster feedback for business decisions.
  • CI improves overall accountability and communication between the teams.

 

To leverage all the benefits of continuous integration, you must implement its best practices. Here are some continuous integration best practices.

IV. Continuous Integration best practices

For best results, continuous integration relies on these best practices:

  • Maintaining the code repository
  • Automating the build
  • Test-driven development
  • Implementation of code request and review
  • Optimizing the pipeline speed
  • Test in a clone of a production environment
  • Maintain high transparency in the process
  • Automate the deployment

3. Continuous Testing

Continuous Testing can be repositioned anywhere around the continuous integration phase in the DevOps lifecycle. Some organizations place it before continuous integration, while most place it after integration.

In the continuous testing phase, the developed software is continuously tested for bugs. A test environment is created with the help of Docker and Containers. Automated tests are run, and reports are generated for the test evaluation process. This process saves a lot of time and manual effort. Also, analyzing the failed test cases becomes easy. At last, a UAT (User Acceptance Testing) is done, and the software is bug-free and ready to move to the next phase of DevOps lifecycle.

I. What is Continuous Testing in DevOps

Continuous Testing in DevOps is a process of executing automated tests at every phase of DevOps lifecycle. It is part of a continuous software delivery pipeline to get immediate feedback on business risks. It involves test automation to speed up software development and delivery.

II. Benefits of Continuous Testing

There are a lot of benefits of continuous testing in Devops. Some of them are as follows:

  • Faster, continuous, and reliable feedback
  • Minor code changes
  • Faster MTTR (Mean Time To Resolution)
  • Faster software release
  • Early bug and error detection
  • Less time needed for code review
  • Resource-saving while implementing CI
  • Mitigate risk at early stages of development

4. Continuous Monitoring

In this phase of DevOps life cycle, we monitor the performance of application. The important and vital information related to the software is recorded here. This information is then used to organize the functionalities of the entire application. Errors such as ‘server not reachable’ or ‘low memory’ are resolved in this phase. Also, the root cause of the issues are found and fixed. Other network-related problems are also taken care of in this phase of DevOps lifecycle.

 

I. What is Continuous Monitoring in DevOps

Continuous Monitoring in DevOps is a technology and process implemented by the DevOps team to rapidly detect security risks and compliance issues in IT infrastructure. Continuous Monitoring empowers DevSecOps teams with real-time information at each phase of the DevOps pipeline.

5. Continuous Feedback

The improvements done in continuous monitoring are analyzed here. Developers can gauge the outcome of the final version of the software. The experiences of a software tester and end clients are shared in this phase. As a result, this can be a turning phase of the project in DevOps lifecycle. The feedbacks are addressed, and changes are made accordingly. Once all the changes are implemented, the DevOps team moves forward to release the new version of the software.

I. What is Continuous Feedback in DevOps

Continuous Feedback in DevOps is an approach to provide new applications directly to the line of business. It is not just an end process but a continuous phase in DevOps lifecycle. It manages coordination between teams through development, deployment, and support in IT as well as non-IT functions.

6. Continuous Deployment

Continuous Deployment is a phase where finalized code is deployed to the production servers. The key aspect of the continuous deployment phase is configuration management. It helps to deploy code on all the servers, which creates consistency in the application. Code is released to the server, and updates are scheduled accordingly. Overall, what continuous deployment does is make an application easy to run on different computers.

 

Continuous Deployment

I. What is Continuous Deployment in DevOps

Continuous Deployment in DevOps is a software release process in which any code that passes the automated testing phase is released into the production environment. These changes are directly reflected to the end software users. Deployment tools can automate the entire deployment process so engineers can focus on other important tasks.

7. Continuous Operations

Continuous Operations is the last and the shortest phase of DevOps lifecycle. The main aim of continuous operations is to automate the release of software and its updates. The development cycle in this phase of DevOps is short, allowing engineers a faster time to market the product.

I. What is Continuous Operations in DevOps

Continuous Operations in DevOps means the operations of data services and applications need to be done continuously without any interruptions. In this phase of DevOps, you need to take care that the availability and performance of an application should not suffer from new updates and releases. There must be no downtime for the application.

Now you know what is DevOps and how it works; let’s understand why people choose devops. More IT organizations are shifting to the DevOps culture, and the reason behind this is the advantages it offers. There are numerous benefits of DevOps for business organizations. Let’s take a look at them one by one.

Benefits of DevOps

When development and operation teams are combined as DevOps, they reduce time, deploy frequently, and develop high-quality software. Organizations that adopt DevOps function in an effective way. DevOps organizations can deliver with speed, innovation, and the latest functionality. DORA’s State Of DevOps Report shows that top DevOps performers deliver code faster, have fewer issues, and solve problems quickly.

Apart from these, there are so many benefits of DevOps. Majorly these benefits can be divided into three categories. Let’s take a look at each of DevOps benefits one by one.

 

Benefiits of DevOps

1. Technical Benefits of DevOps

Here are a few technical benefits of DevOps:

DevOps Tools: creating A DevOps Toolchain

DevOps is not a technology or a singular framework but a cultural practice to be implemented or rather adopted. To follow DevOps culture, you often need to use DevOps tools. So let us understand what is DevOps tooling.

 

What is DevOps Tools

DevOps tools is an umbrella terminology that collectively includes platforms, tools, applications, and servers of SDLC in the DevOps model. The main aim of DevOps tools is to streamline, automate and shorten the various phases of the software delivery pipeline (SDLC).

These DevOps tools help teams to manage complex environments and keep the DevOps engineers in control of the high velocity of DevOps. Many DevOps tools are used to integrate and collaborate between the operation and development teams.

What is DevOps Toolchain

A DevOps toolchain is a collection of tools from different vendors that operate as an integrated unit to build, design, manage, operate, and measure software systems. DevOps toolchain allows DevOps engineers to collaborate through the development lifecycle.

The DevOps toolchain cares about all the fundamentals of DevOps, such as automation, continuous integration, continuous delivery, and collaboration.

DevOps Tools list according to DevOps Lifecycle

Since DevOps is a culture to adopt, there is no singular tool that enables entire DevOps practices and principles. Instead, you need to create a DevOps tools list for each phase of the DevOps lifecycle. There are different types of DevOps tools. Let’s take a look at the best DevOps tool list.

DevOps Tools

1. Continuous Deployment Tools

Continuous deployment tools are automated software that make every code pass through the entire delivery pipeline and release it to the production environment. Once the code is tested by the testing team, continuous deployment tools will automatically pass it to the production environment.

There are multiple deployment tools in the market, but the few that stand apart from others and are considered the best deployment tools are:

3. Microservices

Microservice architecture is a design approach where a single application is built as a set of small services. Each of these small services is called a microservice and can be deployed and operated independently from each other. Each microservice communicates with the other through the Application Programming Interface (API). Microservices are built around business needs and capabilities. Each service is scoped to a sole purpose. The main benefit of microservice is that you can use different frameworks, tools, and programming languages. Also, they can be deployed independently as well as a group of services.

5. Monitoring and Logging

Monitoring and logging, also known as continuous monitoring, is a DevOps practice in which the Devops team monitors the entire Software Development Lifecycle (SDLC). Each phase of the DevOps lifecycle from planning, development, integration & testing, deployment to operation is monitored in this DevOps practice. It allows teams to have full-time visibility on the entire performance and health of an application.

Organizations can understand how updates and changes have affected the end user’s experience by collecting, categorizing, and analyzing the data and logs. This also helps in getting to the root cause of the problems and figuring out the unexpected changes. Whereas performing real-time analysis and creating alerts helps to monitor more proactively.

6. Communication and Collaboration

Increasing collaboration and communication in an organization is a key DevOps practice. By implementing DevOps tooling and automation, the development and operations team collaborate and communicate easier and better. Through project tracking systems, chat apps, and wikis, DevOps teams set strong cultural norms and information sharing. This helps to speed up the communication across operations, development, and other teams like marketing and sales. The overall communication and collaboration practice in DevOps allows different teams in organizations to work more closely on achieving the end goals of a project.

7. Situational Awareness

It is of utmost necessity for every team member to have access to data to complete their jobs quickly and effectively. Team members also need to be aware of the failures in the delivery pipeline and receive timely updates on the performance and health of an application. DevOps metrics, traces, logs, monitoring, and alerts are all vital sources of feedback for situational awareness.

8. Automation

Automation is one of the most important DevOps practices. It helps DevOps teams to move quickly through the software development process. By implementing the automation in your organization, tasks such as code changes can be done through automated builds in no time. Other processes such as repository management, testing, deployment can easily be automated to save time and resources.

Apart from these DevOps best practices, IT security also plays an important role. Let us learn about the security in DevOps.

 

DevSecOps: The security in DevOps

DevSecOps is a new term in application security. It is all about introducing security in every phase of the software development life cycle (SDLC). DevSecOps expands the collaboration between development and operations teams by including the security team as well. Let’s see what DevSecOps actually is.

What is DevSecOps

DevSecOps represents a necessary evolution in which organizations can represent security. In simple terms, DevSecOps can be defined as a combination of Development, Security, and Operation. From design to delivery, DevSecOps integrates security at every phase of the DevOps lifecycle.

 

DevSecOps

In earlier days, security was implemented at the end of SDLC by a separate security team, and then a Quality Assurance (QA) team was used to test it. This was quite manageable when updates were released only once in a while. But now, software developers have adopted Agile, and DevOps approaches. This resulted in a bottleneck situation for the security team.

Thus DevSecOps was introduced to streamline IT security. It addresses the security issues as they emerge and fix them at the initial stage. Apart from this, DevSecOps made security a shared responsibility of all teams rather than solely depending upon the security team.

 

Let us understand the differentiation between DevOps and DevSecOps.

 

DevSecOps vs DevOps

The concepts of DevOps and DevSecOps seem to be very similar, but there is a very thin difference between them. Here is a clear to cut comparison of DevSecOps vs DevOps.

 

DevSecOps VS DevOps 
Comparison criteria DevSecOps DevOps
Main Purpose DevSecOps aims to provide a secure process of the entire development. DevOps aims to bridge the gap between teams to speed up the development process.
Security Application security is taken care of right from the beginning of development. Security is implemented right after the development pipeline.
Automation DevSecOps uses automation mainly for security testing. DevOps uses automation for releasing code into higher environments.
Advantage Detects bugs in early stages and reduces risks. Focuses on simplifying and faster development through collaboration.
Major Processes
  • Common Weakness Enumeration (CWE)
  • Threat Modeling
  • Automated Security Testing
  • Incident Management
  • Continuous Integration
  • Continuous Delivery
  • Continuous Deployment
  • Monitoring
  • Infrastructure as Code

 

From the above comparison of DevSecOps vs DevOps, the difference between them would be clear. Yet, there is much more to learn about DevSecOps. But do not worry, we have covered it all here.
